    摘要： In examples, Radio Frequency Iterative Time-Reversal (RF-ITR) and singular value decomposition (SVD) are used by an array of nodes to characterize environment by identifying scatterer objects. The array may be ad hoc dynamic or stationary. The environment is cancelled from the RF-ITR by adjusting Time-Reversal (TR) prefilters, reducing illumination of the scatterer objects in the environment. This enables the RF-ITR process to focus on a moving target, which can then be sensed (discovered, identified, monitoring, tracked, and/or imaged). The moving target on which the RF-ITR process focuses may then be cancelled from the RF-ITR in the same way as the environment, allowing the RF-ITR to focus on another target. Multiple moving targets can thus be sensed. Defensive measures such as jamming may then be taken against the targets. The targets may be distinguished from the scatterer objects in the environment through differential, Doppler processing, and other classification techniques.

    摘要： A system for transmitting a wireless countermeasure signal to disrupt third party communications is disclosed that include an antenna configured to receive wireless signals and transmit wireless counter measure signals such that the wireless countermeasure signals are responsive to the received wireless signals. A receiver processes the received wireless signals to create processed received signal data while a spectrum control module subtracts known source signal data from the processed received signal data to generate unknown source signal data. The unknown source signal data is based on unknown wireless signals, such as enemy signals. A transmitter is configured to process the unknown source signal data to create countermeasure signals and transmit a wireless countermeasure signal over the first antenna or a second antenna to thereby interfere with the unknown wireless signals.

    摘要： Portable noise generator apparatuses and methods may be used to mask sounds in a hunting area. A noise generator apparatus may have a portable housing configured to be used by a hunter in a hunting area where game may be present, a loudspeaker positioned in the housing, and an electronic noise generator held within the housing. The electronic noise generator may be used to output noise through the loudspeaker to mask sounds made by the hunter while in the hunting area, and the noise may comprise frequencies perceptible by a non-human species. The noise may include white noise and ambient noise that is capable of limiting or covering the sounds of the hunter perceived by game animals.

    摘要： An apparatus (100) includes a canine harness (101) with a radio frequency inhibitor (400). A leash (1002) can serve as a control device (102). The leash can selectively mechanically couple to the canine harness and electrically couple an actuator (114) to the radio frequency inhibitor. When the actuator is actuated, the radio frequency inhibitor is to emit one or more radio frequency inhibition signals (405), which can include the emission of all programmed signals simultaneously. Radio frequency inhibitors can also be integrated into clothing or armor (1802), as well as equipment (1901). The radio frequency inhibitor can interrupt, suppress, or halt electronic detonation communications to an explosive device.
